Love this idea.
I think "users will just use more outputs" is the one argument against. But with witness size not limited in this way, I don't see that being a problem.
If this avoids any of the fiddliness involved in avoiding DOS with GCC, I think we should do it.
Best,
Brandon

I think after 15 years and not having discovered use for 'large' ScriptPubkeys; the reward for not invalidating them at the consensus level is lower than the risk of their abuse.
